Last night the A-listers dressed up to the nines and attended the American Music Awards - the biggest fan-voted award show. Gigi Hadid played host, alongside Jay Pharoah, and there were performances from Justin Bieber, John Lengend, Ariana Grande and Nicki Minaj, Bruno Mars and The Weeknd. Among the winners were Selena Gomez, Beyonce, Adele, Ariana Grande, Zayn and Justin Bieber. Rihanna took home three awards: Favourite Soul/R&B Female Artist, Favourite Soul/R&B Album (for 'Anti') and Favourite Soul/R&B Song (for 'Work' ft. Drake).
Pop princess Selena won the award for Favourite Pop/Rock Female Artist and gave an inspirational and heartfelt speech about her battle with mental health. She looked beautiful in a understated red Prada dress and Giuseppe Zanotti heels.
Supermodel Gigi Hadid made 10 outfit changes throughout the evening. Our favourites were her white lace Roberto Cavalli gown and her Jessica Rabbit-esque floor-length sequin gown by Atelier Versace.
The boys brushed up well too. Ex-Directioners Niall Horan and Zayn Malik both attended the award ceremony, with Niall performing his new solo song, 'This Town', and Zayn collecting an award for New Artist Of The Year. It wasn't certain how harmonious the boys were though, as Zayn made a little dig at Niall and the other former One Direction members whilst collecting his award, saying, 'Wow. This just has my name on it, right?'.
